To date, the most widely used drugs in our anticoagulation clinics are acenocoumarin and warfarin, which belong to the category of vitamin K antagonists (VKA). They have about 70 years of use in the clinic, with proven efficacy for various thrombotic diseases, but also with known problems of variability and dietary and drug interactions. In hospital thromboprophylaxis, the most widely used anticoagulant is enoxaparin, a low molecular weight heparin (LMWH). A new generation of anticoagulants are available, the direct thrombin inhibitors (dabigatran) and factor Xa inhibitors (rivaroxaban and apixaban), with obvious advantages over conventional anticoagulants. This paper summarizes what has been published to date for these new antithrombotics.

Objective: The study aimed to assess the effect of a symbiotic gel on presence and severity of gastrointestinal symptoms (GIS) in hemodialysis patients. Design: A double-blinded, placebo-controlled, randomized, clinical trial was designed. The study was conducted at 2 public hospitals in Guadalajara, Mexico. Subjects and Intervention: Twenty-two patients were randomized to the intervention group (nutritional counseling+symbiotic gel) and 20 patients were randomized to the control group (nutritional counseling+placebo), during 2months of follow-up. Main Outcome Measure: Presence and monthly episodes of GIS were assessed by direct interview and severity by using the self-administered GIS questionnaire. Additionally, biochemical parameters, inflammatory markers, and nutritional status (dietary intake, subjective global assessment, anthropometry, and body composition) were evaluated. Results: After a 2-month treatment, intervention group had a significant reduction in prevalence and monthly episodes of vomit, heartburn, and stomachache, as well as a significant decrease in GIS severity compared with control group. Moreover, intervention group had a greater yet not significant decrease in the prevalence of malnutrition and a trend to reduce their C-reactive protein and tumor necrosis factor α levels compared with control group. No symbiotic-related adverse side effects were shown in these patients. Clinical studies with longer follow-up and sample size are needed to confirm these results. Conclusions: We concluded that administration of a symbiotic gel is a safe and simple way to improve common GIS in dialysis patients. © 2015 National Kidney Foundation, Inc.

Introduction: Aspirin (ASA) irreversibly inhibits platelet cyclooxygenase-1 (COX-1) leading to decreased thromboxane-mediated platelet activation. The effect of ASA ingestion on platelet activation, thromboxane generation, oxidative stress and anti-oxidant biomarkers was studied in type 2 diabetes mellitus (DM). Material and methods: Baseline and post-ASA samples (100/325 mg x 7 days) were obtained from 75 DM patients and 86 healthy controls for urinary 11-dehydro-thromboxane B2 (11dhTxB2), 8-iso-prostaglandin-F2α (8-isoPGF2α) and serum sP-Selectin, nitrite (NO2 -), nitrate (NO3 -) and paraoxonase 1 (PON1) activity. Results: Compared to baseline controls, baseline DM had higher mean levels of 11dhTxB2 (3,665 ± 2,465 vs 2,450 ± 1,572 pg/mg creatinine, p = 0.002), 8-isoPGF2α (1,457 ± 543 vs 1,009 ± 412 pg/mg creatinine, p < 0.0001), NO2 - (11.8 ± 7.3 vs 4.8 ± 5.3 μM, p < 0.0001), NO3 - (50.4 ± 39.3 vs 20.9 ± 16.7 μM, p < 0.0001) and sP-Selectin (120.8 ± 56.7 vs 93.0 ± 26.1 ng/mL, p = 0.02), and the same held for post-ASA levels (p < 0.0001). ASA demonstrated no effect on 8-isoPGF2α, NO2 -, NO3 -, sP-Selectin or PON1 activity in either DM or controls. Post ASA inhibition of urinary 11dhTxB2 was 71.5% in DM and 75.1% in controls. There were twice as many ASA poor responders in DM than in controls (14.8% and 8.4%) based on systemic thromboxane reduction. Urinary 8-isoPGF2α excretion was greater in DM ASA poor responders than good responders (p < 0.009). Conclusions: This suggests that oxidative stress may maintain platelet function irrespective of COX-1 pathway inhibition and/or increase systemic generation of thromboxane from non-platelet sources. © 2012 Elsevier Ltd.

Immunologic and inflammatory processes are involved in the pathogenesis of acute coronary syndrome (ACS) and type 2 diabetes mellitus (DM2). Human leukocyte antigen-G (HLA-G) is a negative regulator of the immune response. This study evaluates the 14 bp Del/Ins HLA-G polymorphism in ACS and DM2. Three hundred and seventy individuals from Western Mexico were recruited and categorized into three groups: ACS (86), DM2 without coronary complications (70), and healthy subjects (214). Genotyping of the 14 bp Del/Ins HLA-G polymorphism was performed by PCR and Native-PAGE. The most common risk factors were hypertension and overweight in ACS and DM2, respectively. The genetic distribution of the 14 bp Del/Ins HLA-G polymorphism showed no significant differences between groups (P ≥ 0.23). Nonetheless, the Ins/Ins genotype was associated with high blood pressure (HBP) in the DM2 group (OR c = 1.65, P = 0.02). The genetic recessive model showed similar findings (OR c = 3.03, P = 0.04). No association was found in ACS, with a P of 0.05; nevertheless, the prevalence of Ins/Ins carriers was quite similar to that found in the DM2-HBP group. The 14 bp Del/Ins HLA-G polymorphism was not a susceptibility factor for ACS or DM2; however, the Ins/Ins genotype might have contributed to the development of HBP in the studied groups. © 2014 Ilian Janet García-González et al.

This article describes a 19-year-old female with mild facial dysmorphism, asociality, decreased school performance, and psychotic behavior in whom the karyotype showed an extra-chromosomal marker characterized as 9p24.3-9q21.11 duplication by array-CGH. The 69. Mbp duplicated segment in this patient includes the critical 9p duplication syndrome region, the GLDC and C90RF72 genes associated with psychotic behavior and other conduct disorders, and a potential locus for autism. © 2015 Elsevier B.V.
